INTRODUCTION
This chapter describes the GPI-6 general-purpose inputs interface.
System operators can use this chapter once the Eclipse system has
been correctly installed and the input controls have been assigned with
the Eclipse Configuration System programming software.
DESCRIPTION
The GPI-6 provides six general-purpose logic inputs into the matrix,
allowing external sources to trigger routing changes and other events
through the matrix system. Like the RLY-6, this interface is also
connected through the separate RJ-45 accessory data connector on
the matrix frame.
Multiple GPI-6 interfaces can be daisy-chained to provide connection
of up to 60 inputs to the matrix. RLY-6 and GPI-6 modules can be
mixed together up to the total limit of 60 items. Five RLY-6 and five
GPI-6 modules would provide 30 relays and 30 inputs for a total of 60
ins and outs.
For Eclipse systems if both GPI-6 and RLY-6 interfaces are used the
GPI-6 interfaces are required to be placed first in the daisy chain. This
restriction does not apply to Matrix Plus 3 systems.
All of the RLY-6 and GPI-6 interfaces in the system are daisy-chained
from the GPI/RLY connection. The matrix system will automatically
identify both the type and "addresses" of every relay output or logic
input.
The GPI-6 provides the following functions:
1. Senses six independent sets of logic inputs which can activate
functions in the matrix frame as defined by the configuration
program.
2. DC isolation between the external device(s) and the system.
3. An LED indicator for each input that lights when the input is active.
Each GPI-6 interface input will sense a voltage between 5 to 45 volts of
either polarity. Over this voltage range the maximum signal current
drawn by the card will be 7 mA.
The LED indicators for each input actually indicate what the matrix
system has read from the inputs so that these indicators show that the
interface is really working.
A TEST pushbutton switch is provided for each input to allow local
activation of the software function associated with the input.
The GPI-6 provides six
general-purpose logic inputs.
• You can “daisy-chain”
GPI-6 and RLY-6 units to
provide more inputs and
outputs to the matrix.
